What does SparkTower's simulator pay to open it?
The simulator pays the one-off opening costs before the first customer — the running costs and the founder's living it plays month by month: Office fit-out $10,000; Lease deposit (two months' rent) $2,500; Practice software and IT $6,000; Malpractice insurance and bar fees $5,000; Forming the firm $2,000; Website and marketing $7,000. A solo law practice: $10k–$50k (Clio's solo-practice startup guide; ABA solo practice resources); malpractice cover $1k–$5k a year. Plus the lease: a deposit of about two months' rent (two to three is usual for a first US tenant, and restaurant landlords ask for at least two — Aquila Commercial; REBusiness, restaurant lease counsel).
How much of that do you keep?
$16,000 of it — the kit, fit-out or stock it bought — is still yours afterwards, something a buyer would pay for and a lender would lend against; the other $16,500 is spent.
What if my own money doesn't cover it?
With $10,000 of your own you would be about $31,600 short. Borrowed as an SBA microloan at 11% over 5 years, that is about $687 a month. Most founders borrow the rest. A small-business term loan runs about 11% a year over 5 years (SBA 7(a) loans are the prime rate plus 3 to 6.5 points), repaid every month from the start — before the business has found its customers. In SparkTower's law firm simulator the founder starts with $30,000 of their own money. The launch costs take all of it and $10,625 is borrowed — at 11% over 5 years, about $231 a month from the first period.
Can you start a law firm with no money?
Not in full: lenders want the owner to put in about 20% (the SBA's own floor for a start-up is 10%), and lend against the kit, fit-out and stock a launch buys, not its marketing or a software build. What a founder with nothing does is open smaller — a virtual solo practice — on about $4,800 of essentials (practice software $1,500; malpractice insurance and bar fees $3,000; forming the firm $300), borrowed as a microloan (the SBA's are up to $50,000, at 8–13%) or, for a few thousand dollars, on a card at about 22%. The rest is bought once the business can afford it. A virtual solo practice: $3k–$10k (Clio solo-practice guide), malpractice cover $1k–$5k a year.
Will it earn the money back?
That depends on what you charge, how many customers you win and what your rivals do. The free law firm simulator pays these costs before it opens, borrows what the founder's cash doesn't cover, and plays the business forward against real rivals, so you can see whether it earns them back before you spend them.
